5: Peak LED. This LED flashes when the signal level into the preamp approaches clipping. Adjust the Gain control (#4) until a strong signal from your instrument causes this LED to flash. 6: Low. This serves as the instrument channel’s primary bass control. Adjust this control to get the best sounding bass response for your instrument. Excessive boost of the low control can cause an unnatural howling and should be avoided. 7: Mid. This serves as the instrument channel’s primary midrange control. Adjust this control to get the best projection and midrange tones for your instrument. 8: High. This serves as the instrument channel’s primary treble control. Adjust this control so your high notes and harmonic overtones are lively but not overpowering. 9: Freq. Use this control along with the Cut control (#10) to eliminate instrument feedback. For information on the proper use of this control, please read the section entitled “To Eliminate Instrument Feedback.” 10: Cut. Use this control along with the Freq control (#9) to eliminate instrument feedback. For information on the proper use of this control, please read the section entitled “To Eliminate Instrument Feedback.” 11: Rev/Eff send. Use this control to adjust the amount of internal reverb and/or external effect (if used) for the instrument channel. 12: Chorus On/Off switch. This switch, when depressed, applies the internal chorus effect to the instrument channel. 13: Chorus Depth. Use this control to adjust the magnitude of the chorus effect. Rotating this control clockwise increases the intensity of the effect. 14: Chorus Rate. Use this control to adjust the rate of the chorus effect. Rotating this control clockwise increases the rate at which the effect occurs. The Vocal/Aux channel: 15: Low-Z input. The signal output from a low impedance microphone may be connected here by means of a shielded, balanced microphone cable terminated with an XLR connector. 16: Hi-Z input. The signal output from a high impedance microphone or a line level signal may be connected here by means of a shielded signal cable terminated with a 1/4” tip/sleeve connector. 17: Phantom Power switch. This switch, when depressed, applies 15 volts phantom power to pins 2 and 3 of the Low-Z input jack (#15), for proper operation of microphones requiring phantom power. (Mics not needing phantom power will not be affected by this switch.) 18: Chorus On/Off switch. This switch, when depressed, applies the internal chorus effect to the vocal/aux channel. (Chorus is only available for this channel when the instrument channel’s chorus switch, #12, is depressed.) 19: Gain. This serves as the input level control for the vocal/aux channel of the amplifier. Adjust this control for the best mix with the signals from the instrument channel. 20: Low. This serves as the vocal/aux channel’s primary bass control. Adjust this control to get the best sounding bass response for this channel. Excessive boost of the low control can cause an unnatural howling and should be avoided. 21: High. This serves as the vocal/aux channel’s primary treble control. Adjust this control so the high notes and harmonic overtones are lively but not overpowering. 22: Rev/eff send. Use this control to adjust the amount of internal reverb and/or external effect (if used) for the vocal/aux channel. The Master Section: 23: Rev Return. Use this control to adjust the amount of internal reverb – rotate the control clockwise to increase the effect, counter-clockwise to decrease it. 24: Level. Use this control to set the overall output level of the amplifier. 25: Power Switch. Use this switch to apply power to the amplifier: the amp is on when the top of the switch is depressed, off when the bottom of the switch is depressed. This switch will illuminate when the amplifier is on. On the Rear Panel: 0 10Return SendLevel 0 10 Low Z Bal. High ZBal.

This switch, when depressed, deactivates the CA60’s internal tweeter. 27: Footswitch. Connect the supplied two-button footswitch here for remote on/off control of the internal reverb and chorus. (When connected, the footswitch overrides the front panel chorus on/off switch.) Note: This is a STEREO jack: tip controls the chorus, ring controls the reverb, sleeve is ground. Use only a footswitch equipped with a stereo 1/4” plug. 28: Effects Loop Send. When using an external signal processor, connect this jack to the input of the effect by means of a shielded signal cable. 29: Effects Loop Return. When using an external signal processor, connect this jack to the output of the effect by means of a shielded signal cable. 30: Ground Lift. This switch, when depressed, electronically disconnects the low Z balanced output jack’s chassis ground connection. If you experience excessive noise when using the low Z balanced output jack, depress this switch. 31: High Z Bal. Use this jack to con...
